keyboard_clearstate(3) Svgalib User Manual keyboard_clearstate(3)
NAME
keyboard_clearstate - reset the state of all keys when in
raw keyboard mode
SYNOPSIS#include<vgakeyboard.h>voidkeyboard_clearstate(void);DESCRIPTION
When in raw keyboard mode, svgalib receives press and
release events from the kernel and keeps track which keys
are currently pressed. Calling keyboard_clearstate() sets
this information to all keys released. You can use this
for cleanup at certain places in your program. In addition
svgalib resets the states of all keys when a VC switch
occurs because it does not know the current state of keys
when it regains control of the console.
